I lived at a field station in Panama for almost two years in total. But per the OP’s most recent post that probably counts as “home,” although I lived in various rooms at the station at different times.
There was another field station in New Zealand where I spent two weeks out of every six in the bunkhouse for more than two years.
There have been a number of field camps in South America and Peru where I spent several weeks to a couple of months total at each one.
I used to exhibit at a series of outdoor shows in the Pacific Northwest that basically ran 5 cities in 5 weeks. Leave one and move on to the next basically 6 or 7 nights at each location. Going Red Roof and with many of the rooms looking basically the same, sometimes I woke up in the middle of the night not remembering just where I was. :smack:
There was boot camp/basic but I don’t think that is what the OP was looking for.
I worked for a temp agency for a while, and there are several motels I stayed at during the week for a couple months on end.
I lived in a dorm for my first year of college.
Excluding things like university residences, I stayed in a hotel for three months while I waited to sell my house.
My job started in City A, my house remained on the market in City B, and I had to be at work. So I got a hotel room in City A. Long story short, I sold my house in City B, and bought a house in City A, living in a hotel room all the while.
It was fun at first, but soon became tiresome. I missed my things, I missed my cats (they were being looked after by a friend back in City B), I missed a home routine. I was never so glad to take possession of my house in City A, move everything (including my cats), and settle back into home life.
I stayed three months or so in a hotel in Malta back in the summer of 2001.
I was in a womb for 9 months.
5 years in the Air Force and I never considered it a home.
I presume you mean extended time in more or less the same place. I’ve been on four different International trips of 7 months or more without ever touching any kind of base, but rarely staying for more than a week or two in the same place…
ummm…don’t we have a couple of members here who done time in jail? 
But for me: does 5 days a week count?
I came home on weekends, but for 4 months I lived in a Motel 6 for work.
Same motel every week, but for variety,it wasn’t always the same room. Whoopee!
Several long stints during my oil rig days, but the longest uninterrupted was 120 days on the Semac 1. That summer was also the longest I’ve gone without seeing land, driving a car, talking on a phone or watching TV (103 days).
Other than that, I spent slightly over a month in Santa Monica on a lengthy business trip.
For non-business related, we’ve spent 3 weeks in our RV, but moved around a lot.
Residential Care Center for Adults (RCCA) was a facility for homeless people in Queens, so I’d think it counts as “not my home” (?) and I was in a room from April 1985 to Sept 1986.
Do dorm rooms count? A year on campus in the same dorm room 1986-87 at SUNY / Old Westbury. (The following year I changed rooms during the year so it’s not the “same place”).
From Sept to mid-Nov of 1980 I lived in a campground in Rangely CO. (lower left corner, Elk Park). I was an itinerant worker.
A bit over a month in One Life commune in Topanga Canyon CA outside LA also in 1980.
The Sahar hotel in Dubai. It’s a 2-star place near Nasr Square (Beniyas Square) and I have probably spent a total of 12 weeks there. Most of that time was in 2002-2004.
Drilling rig camp in Guatemala, around '85 or so. Over the course of a year, probably spent five months in total there. Longest individual stretch was seven weeks. Did numerous 3-4-week hitches on rig sites in the Rocky Mountains, Peru, Ecuador, Tunisia, and Angola.
From 2013-15, I was working on a documentation project that had me going to Paris for two weeks at a time, every other month. I always stayed in the same obscure little hotel in the northeastern suburb of Parc des Expositions.
Excluding where the company leases me a house or apartment, then the Mississauga Residence Inn; I spent 11 months there. The 18 months at Ventura Suits in Huixquilucan/Interlomas is debatable… was it an apartment, or was it a hotel?
On two of my overseas trips, I lived in hotels. Both trips were over a year. The third trip, we were provided a mobile home to live in. That was about 18 months.
Two years in Iraq.
Ft. Riley, KS, while not home home, still counts I think, as my wife and I had on-post housing there and pets, so that was home at least temporarily.
A year each in both Habbaniyah and Balad, Iraq was not home at all, though, temporary or otherwise.
Boarding school. About seven years in total, but the longest stretch in a single building was hereI think.
I’d guess that it’s the Hyatt Regency Columbus (Ohio) – it’s attached to the Columbus Convention Center, which hosts the Origins gaming convention. I’ve stayed there for 4 or 5 nights for the convention, every year since around 2005. So, that adds up to somewhere around 50 to 60 nights.
I used to travel a lot on business, often to the same hotels. One in particular in Silicon Valley, saw me so often that I kept some of my things there so I didn’t have to pack. I think they saw me more often during that time than my family. The hotel got me during the week, and my family got weekends. It amounts to hundreds of days at this one hotel.
